Description

USE OF NATURAL SUBSTANCES FOR THE PRODUCTION OF COSMETIC PREPARATIONS

Field of the Invention

The invention is in the fields of cosmetics and pharmacy and relates on the one hand to the use of certain plant extracts for the production of cosmetic preparations and on the other hand to the use of the extracts as active substances for increasing the activity of certain enzymes in the metabolism and to a method for evaluating active substances against skin aging.

State of the art

Although skin aging has many causes, the active ingredients developed by the cosmetics industry, on the other hand, can basically be divided into two groups. On the one hand there are active ingredients that protect the cells against oxidative stress or proteolysis (protective effect), on the other active ingredients that stimulate cell regeneration (healing effect). The latter in particular have gained in importance in recent years, although their development requires a precise understanding of the biochemical processes in the skin. These active ingredients include, for example, enzymes that counteract damage by UV light or environmental toxins, but also those that prevent the synthesis of essential cell components, e.g. Promote structural proteins, membrane lipids or DNA. Cosmetic preparations on the market already contain substances such as DNA fragments that stimulate IL-6 or P53 activity, proteins to stimulate collagen synthesis or ribosomes from E. coli to stimulate the growth of keratinocytes.

However, the present patent application is based on another finding. Glucose 6-phosphate dehydrogenase (G6PDH) is an enzyme that catalyzes the first steps of the so-called "pentose route". During the first step, the conversion of glucose 6-phosphate (G6P) into 6-phosphogluconate (6PG), G6PDH needs as coenzyme Nicotinamide adenine dinucleotide phosphate (NADP), which is reduced to NADPH 2. The reduced form of this coenzyme can catalyze a variety of enzymatic reactions such as the recycling of glutathione or lipid synthesis. The last step of the pentose route also provides the most important precursor for DNA, deoxyribose According to the investigations by Weber and Körting in J. Invest.Dermatol. 42, 167-169 (1964), G6PDH and 6-phosphatogluconate dehydrogenase (6PGDH) as well as a number of other glycolysis enzymes (eg aldolase) are in the upper layers of human skin. Based on a large number of further studies, the applicant has found that G6DPH not only plays an important role in the metabolism of the skin, but can also serve as an in-vitro model system for the effectiveness of active ingredients against skin aging.

The object of the present patent application was therefore to provide those active substances which stimulate the activity of G6PDH in the fibroblasts, if possible without negatively influencing the DNA content of the cells.

Description of the invention

The invention relates to the use of natural substances selected from the group formed by extracts of plants from the Solanaceae family, the Amaranthaceae family and the Monimiaceae family for the production of cosmetic preparations. Another object of the invention is the use of natural substances selected from the group formed by extracts of plants from the Solanaceae family, the Amaranthaceae family and the Monimiaceae family as active ingredients for producing an agent for increasing the G6PDH activity in the metabolism.

Surprisingly, it was found that the extracts of the plants mentioned and the active principles contained therein fulfill the task in an excellent manner. Compared to the standard, the G6PDH activity could be increased by up to 140% without the DNA content having decreased significantly. The substances are therefore ideally suited for the production of cosmetic preparations, especially skin treatment agents and in particular agents against skin aging.

plant extracts

Typical examples of plants whose extracts can be used in the sense of the invention are

Plants of the Geni Physalis, Achyranthes and / or Peumus.

In a particular embodiment, extracts are accordingly used according to the invention which contain active ingredients which are selected from the group formed by carotenoids, flavone derivatives, phenolic acids, chlorogenic acids, steroids, aporphine alkaloids, sterols and terpenes.

According to the invention, the carotenoids, flavone derivatives, phenolic acids, chlorogenic acids, steroids, aporphine alkaloids, sterols and terpenes, which can be extracted from the preferred plants Geni Physali, Achyranthes and Peumus, are preferably used. For the plants of the genus Physalis, the preferred active substances include the steroids Physalin A, Physalin B, Physalin C, Physalin D, 5β, 6ß-epoxyphysalin, dihydroxyphysalin B and the steroids Whitaphysalin A, Whitaphysalin B, Whitaphysalin C.

The use of sterols and terpenes from Achyranthes, in particular from Achyranthes bidentata, is particularly preferred.

For the plants of the genus Peumus, the active substances preferred according to the invention include the aporphine alkaloids, in particular boldine. The extracts of the plants mentioned, in particular extracts of the plants Physalis minima, Achyranthes bidentata, Achyranthes aspera and Peumus boldo, the active substances alone or as a mixture in combination of at least two active substances extracted from the plants mentioned can be used as natural substances in the sense of the invention and their preferred selection or the active ingredients can be used alone or in combination of at least two active ingredients extracted from other plants or synthetically produced.

The amount of natural substances or extracts used can be in the range from 0.001 to 5, preferably 0.005 to 1 and in particular 0.01 to 0.5% by weight, based on the composition.

extraction

The extracts can be prepared in a manner known per se, ie for example by aqueous, alcoholic or aqueous-alcoholic extraction of the plants or parts of plants. Regarding the suitable conventional extraction methods such as maceration, remaceration, digestion, movement maceration, vortex extraction, ultrasound extraction, countercurrent extraction, percolation, repercolation, evacolation (extraction under reduced pressure), diacolation and solid-liquid extraction under continuous reflux , which is carried out in a Soxhlet extractor, which is familiar to a person skilled in the art and in principle all can be used, for the sake of simplicity, for example, on Hager's Handbook of Pharmaceutical Practice, (5th edition, vol. 2, pp. 1026-1030, Springer Verlag , Berlin-Heidelberg-New-York 1991). The percolation method is advantageous for large-scale use. Fresh plants or parts of plants can be used as the starting material, but usually dried plants and / or parts of plants are used, which can be mechanically comminuted before extraction. All comminution methods known to the person skilled in the art are suitable here, freeze grinding being mentioned as an example. Organic solvents, water (preferably hot water at a temperature of above 80 ° C. and in particular above 95 ° C.) or mixtures of organic solvents and water, in particular low molecular weight alcohols with more or less high water contents, can be used as solvents for carrying out the extractions become. Extraction with methanol, ethanol, pentane, hexane, heptane, acetone, propylene glycols, polyethylene glycols and ethyl acetate as well as mixtures thereof and their aqueous mixtures is particularly preferred. The extraction is usually carried out at 20 to 100 ° C, preferably at 30 to 90 ° C, in particular at 60 to 80 ° C. In a preferred embodiment, the extraction takes place under an inert gas atmosphere to avoid oxidation of the active ingredients of the extract. This is particularly important for extractions at temperatures above 40 ^° C. The extraction times are set by the person skilled in the art depending on the starting material, the extraction process, the extraction temperature, the ratio of solvent to raw material, etc. provides. After the extraction, the crude extracts obtained can optionally be subjected to further customary steps, such as purification, concentration and / or decolorization. If desired, the extracts produced in this way can, for example, be subjected to a selective separation of individual undesirable ingredients. In a preferred embodiment, the extracts are subjected to fractionation. Fractionation by liquid chromatography on synthetic resins based on ion exchange resins or adsorber resins, in particular on Amberlite XAD, is particularly preferred. The fractionation is preferably carried out using a step gradient of the eluent. Preferred solvent mixtures which can be used as eluents with a step gradient are water / methanol, water / ethanol, water / isopropanol and methanol / acetone. In the case of the aqueous mixtures, a mixture of 20% by weight of aqueous methanol is preferably started and the mixture is gradually changed to 100% by weight of methanol. In this way, different fractions are obtained, which can be classified according to the mixing ratio of the solvent mixture. Depending on the polarity of the solvent mixture, differently polar ingredients of the extract are eluted and fractionated. The extraction can take place to any degree of extraction, but is usually carried out to exhaustion. Typical yields (= amount of dry matter of the extract based on the amount of raw material used) in the extraction of dried leaves are in the range from 3 to 15, in particular 6 to 10,% by weight. The present invention encompasses the knowledge that the extraction conditions and the yields of the final extracts can be selected by the person skilled in the art depending on the desired field of use. These extracts, which as a rule have active substance contents (= solids contents) in the range from 0.5 to 10% by weight, can be used as such, but it is also possible to add the solvent by drying, in particular by spray or freeze drying remove. The extracts can also serve as starting materials for the production of the above-mentioned pure active ingredients, provided that these cannot be produced more easily and inexpensively by synthetic means.

Accordingly, the active substance content in the extracts can be 5 to 100, preferably 50 to 95% by weight. The extracts themselves can be present as aqueous and / or preparations dissolved in organic solvents and as spray-dried or freeze-dried solids. Examples of suitable organic solvents in this context are the aliphatic alcohols with 1 to 6 carbon atoms (e.g. ethanol), ketones (e.g. acetone), halogenated hydrocarbons (e.g. chloroform or methylene chloride), lower esters or polyols (e.g. glycerol or glycols).

In a preferred embodiment of the invention, the natural substances and / or extracts mentioned are used as agents against skin aging. Another term for this type of remedy is anti aging. These signs of aging include any type of wrinkles and wrinkles. Treatments include slowing skin aging. The increase in G6PDH activity in the metabolism leads to the use of the natural substances according to the invention as agents against skin aging. The signs of aging can have a variety of causes. Another object of the invention is the use of natural products selected from the group formed by carotenoids, in particular retinol and retinoic acid, flavone derivatives, phenolic acids, chlorogenic acids, steroids, aporphine alkaloids, sterols and terpenes as active ingredients for the preparation of an agent for Increase in G6PDH activity in metabolism. The natural substances can be extracted from other plants or produced synthetically. The amount of natural substances used can be in the range from 0.001 to 5, preferably 0.005 to 1 and in particular 0.01 to 0.5% by weight, based on the composition.

The present invention further relates to a method for determining the effectiveness of an agent against skin aging, in which the influence of the active ingredient on the activity of glucose-6-phosphate dehydrogenase in fibroblasts is determined.

Typical examples of fats are glycerides, i.e. Solid or liquid vegetable or animal products, which consist essentially of mixed glycerol esters of higher fatty acids, come as waxes, among others. natural waxes, e.g. Candelilla wax, camauba wax, japan wax, esparto grass wax, cork wax, guaruma wax, rice germ oil wax, sugar cane wax, ouricury wax, montan wax, beeswax, shellac wax, walrate, lanolin (wool wax), pretzel fat, ceresin, ozokerite (earth wax), petrolatum, paraffin waxes, microfax waxes chemically modified waxes (hard waxes), e.g. Montanester waxes, Sasol waxes, hydrogenated jojoba waxes and synthetic waxes, such as Polyalkylene waxes and polyethylene glycol waxes in question. In addition to fats, fat-like substances such as lecithins and phospholipids can also be used as additives. The person skilled in the art understands the term lecithin those glycerophospholipids which are formed from fatty acids, glycerol, phosphoric acid and choline by esterification.

UV light protection filters and antioxidants

UV light protection factors are understood to mean, for example, organic substances (light protection filters) which are liquid or crystalline at room temperature and which are able to absorb ultraviolet rays and release the absorbed energy in the form of longer-wave radiation, for example heat. UVB filters can be oil-soluble or water-soluble. Examples of oil-soluble substances are: > 3-benzylidene camphor or 3-benzylidene norcampher and its derivatives, for example 3- (4-methylbenzylidene) camphor as described in EP 0693471 B1;

> 4-aminobenzoic acid derivatives, preferably 2-ethyl-hexyl 4- (dimethylamino) benzoate, 2-octyl 4- (dimethylamino) benzoate and amyl 4- (dimethylamino) benzoate;

Derivatives of benzoylmethane, such as 1- (4'-tert-butylphenyl) -3- (4'-methoxyphenyl) propane-1,3-dione, 4-tert-butyl, are particularly suitable as typical UV-A filters -4'-methoxydibenzoyl-methane (Parsol® 1789), 1-phenyl-3- (4'-isopropylphenyl) propane-1,3-dione and enamine compounds as described in DE 19712033 A1 (BASF). The UV-A and UV-B filters can of course also be used in mixtures. Particularly favorable combinations consist of the derivatives of benzoylmethane, for example 4-tert-butyl-4'-methoxydibenzoylmethane (Parsol® 1789) and 2-cyano-3,3-phenylcinnamic acid-2-ethyl-hexyl ester (octocrylene) in combination with Esters of cinnamic acid, preferably 2-ethylhexyl 4-methoxycinnamate and / or propyl 4-methoxycinnamate and / or isoamyl 4-methoxycinnamate. Such combinations are advantageously combined with water-soluble filters such as 2-phenylbenzimidazole-5-sulfonic acid and their alkali, alkaline earth, ammonium, alkylammonium, alkanolammonium and glucammonium salts. In addition to the soluble substances mentioned, insoluble light protection pigments, namely finely dispersed metal oxides or salts, are also suitable for this purpose. Examples of suitable metal oxides are, in particular, zinc oxide and titanium dioxide and, in addition, oxides of iron, zirconium, silicon, manganese, aluminum and cerium and mixtures thereof. Silicates (talc), barium sulfate or zinc stearate can be used as salts. The oxides and salts are used in the form of the pigments for skin-care and skin-protecting emulsions and decorative cosmetics. The particles should have an average diameter of less than 100 nm, preferably between 5 and 50 nm and in particular between 15 and 30 nm. They can have a spherical shape, but it is also possible to use particles which have an ellipsoidal shape or a shape which differs from the spherical shape in some other way. The pigments can also be surface-treated, ie hydrophilized or hydrophobicized. Typical examples are coated titanium dioxides such as titanium dioxide T 805 (Degussa) or Eusolex® T2000 (Merck). Silicones, and in particular trialkoxyoctylsilanes or simethicones, are particularly suitable as hydrophobic coating agents. So-called micro- or nanopigments are preferably used in sunscreens. Micronized zinc oxide is preferably used. Other suitable UV light protection filters are in the overview by P.Finkel in SÖFW-Journal 122, 543 (1996) and Parf.Kosm. 3, 11 (1999).

In addition to the two aforementioned groups of primary light stabilizers, secondary light stabilizers of the antioxidant type can also be used, which interrupt the photochemical reaction chain which is triggered when UV radiation penetrates the skin. Typical examples are amino acids (e.g. glycine, histidine, tyrosine, tryptophan) and their derivatives, imidazoles (e.g. urocanic acid) and their derivatives, peptides such as D, L-camosine, D-camosine, L-carnosine and their derivatives (e.g. anserine) , Carotenoids, carotenes (eg α-carotene, β-carotene, lycopene) and their derivatives, chlorogenic acid and their derivatives, lipoic acid and their derivatives (eg dihydroliponic acid), aurothioglucose, propylthiouracil and other thiols (eg thioredoxin, glutathione, cysteine, Cystine, cystamine and their glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl, γ-linoleyl, cholesteryl and glyceryl esters) and their salts , Dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and its derivatives (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts) as well as sulfoximine compounds (eg buthioninsulfoximines, homocysteine sulfoximine, butioninsulfones, penta-, hexa-, heptathioninsulfoninsulfoninsulfoxins) compatible dosages (e.g. pmol to μmol / kg), also (metal) chelators (e.g. α-hydroxy fatty acids, palmitic acid, phytic acid, lactoferrin), α-hydroxy acids (e.g. citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, Bilirubin, biliverdin, EDTA, EGTA and their derivatives, unsaturated fatty acids and their derivatives (e.g. γ-linolenic acid, linoleic acid, oleic acid), folic acid and their derivatives, ubiquinone and ubiquinol and their derivatives, vitamin C and derivatives (e.g. ascorbyl palmitate, Mg-ascorbyl phosphate , Ascorbyl acetate), tocopherols and derivatives (eg vitamin E acetate), vitamin A and derivatives (vitamin A palmitate) and coniferyl benzoate of benzoin, rutinic acid and its derivatives, α-glycosyl rutin, ferulic acid, furfurylidene glucitol, carnosine, butylated hydroxytisolol, , Northern Hydroguajak resin acid, nordihydroguajaretic acid, trihydroxybutyrophenone, uric acid and its derivatives, mannose and its derivatives, superoxide dismutase, zinc and its derivatives (e.g. ZnO, ZnS0 ₄ ) selenium and its derivatives (e.g. selenium methionine), stilbenes and their derivatives (e.g. Stilbene oxide, trans-stilbene oxide) and the derivatives (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids) of these active substances which are suitable according to the invention.

Deodorants and germ inhibitors

Cosmetic deodorants counteract, mask or eliminate body odors. Body odors arise from the action of skin bacteria on apocrine sweat, whereby unpleasant smelling breakdown products are formed. Accordingly, deodorants contain active ingredients which act as germ-inhibiting agents, enzyme inhibitors, odor absorbers or odor maskers. In principle, all substances effective against gram-positive bacteria are suitable as germ-inhibiting agents, such as. B. 4-hydroxybenzoic acid and its salts and esters, N- (4-chlorophenyl) -N ^' - (3,4 dichlorophenyl) urea, 2,4,4 ^' -Trichlor-2 ^' -hydroxydiphenyl ether (triclosan), 4-chlorine -3,5-dimethyl-phenol, 2,2 ^{'-methylene-bis} (6-bromo-4-chlorophenol), 3-methyl-4- (1-methylethyl) phenol, 2-benzyl-4-chlorophenol, 3 - (4-chlorophenoxy) -1, 2-propanediol, 3-iodo-2-propynyl butyl carbamate, chlorhexidine, 3,4,4 ^' trichlorocarbanilide (TTC), antibacterial fragrances, thymol, thyme oil, eugenol, clove oil, menthol, Mint oil, famesol, phenoxyethanol, glycerol monocaprinate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprinate (DMC), salicylic acid N-alkylamides such as B. salicylic acid-n-octylamide or salicylic acid-n-decylamide.

Esterase inhibitors, for example, are suitable as enzyme inhibitors. These are preferably trialkyl citrates such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and in particular triethyl citrate (Hydagen® CAT). The substances inhibit enzyme activity and thereby reduce odor. Other substances which can be considered as esterase inhibitors are sterol sulfates or phosphates, such as, for example, lanosterol, cholesterol, campesterol, stigma- sterol and sitosterol sulfate or phosphate, dicarboxylic acids and their esters, such as, for example, glutaric acid, monoethyl glutarate, Diethyl glutarate, adipic acid, monoethyl adipate, Diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and their esters such as citric acid, malic acid, tartaric acid or tartaric acid diethyl ester, and zinc glycinate.

Suitable odor absorbers are substances that absorb odor-forming compounds and can retain them to a large extent. They lower the partial pressure of the individual components and thus also reduce their speed of propagation. It is important that perfumes must remain unaffected. Odor absorbers are not effective against bacteria. They contain, for example, a complex zinc salt of ricinoleic acid or special, largely odorless fragrances, which are known to the person skilled in the art as "fixators", such as, for example, the main component. B. extracts of Labdanum or Styrax or certain abietic acid derivatives. Fragrance agents or perfume oils act as odor maskers and, in addition to their function as odor maskers, give the deodorants their respective fragrance. Perfume oils are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts of flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches as well as resins and balms. Animal raw materials, such as civet and castoreum, are also suitable. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are e.g. Benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexyl propionate, styrallyl propionate and benzyl salicylate.

However, preference is given to using mixtures of different fragrances which together produce an appealing fragrance. Essential oils of lower volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. Sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, oliban oil, galbanum oil, labdanum oil and lavandin oil. Bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzyl acetone, cyclamenaldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, citrone oil, mandarin oil, allyl glycolate, orangalol oil, orangol oil, orangol oil, are preferred , Lavandin oil, muscatel sage oil, ß- damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix Coeur, Iso-E-Super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilate, irotyl and floramate alone or in mixtures, alone or in mixtures, used.
